I am looking at these data.

Code: Select all

			"Usage" : "0 Watt",
			"UsageDeliv" : "2900 Watt",

I can extract Usage with

Code: Select all

        local power_usage = dz.devices(POWER).usage

However I cannot extract Delivery to the net.

Code: Select all

 local power_delivery = dz.devices(POWER).usagedeliv

The extraction of data executes without error

Code: Select all

dz.log('Delivery   : ' .. power_delivery, dz.LOG_DEBUG)

However the debug info tells me: cannot concatenate a nil value

The usage gives me values from 0 up to 3000 and more
The delivery, indicated as 2900 gives me this NIL value.

What is the secret code to use other than usagedeliv or change that NIL value bug.

See the documentation https://www.domoticz.com/wiki/DzVents:_ ... mart_meter

P1 Smart meter
counterDeliveredToday: Number.
counterToday: Number.
usage1, usage2: Number.
return1, return2: Number.
updateP1(usage1, usage2, return1, return2, cons, prod): Function. Updates the device. Supports command options.
usage: Number.
usageDelivered: Number.

In fact I am searching for the word UsageDelivered or Delivery or like the code displays UsageDeliv.
None of those delivers a number.
Your link displayed the magic word usageDelivered

It works!
Thanks for the help.
